A closet has the ability to dehumidify, heat and/or circulate the air therein in order to dry clothes. The dehumidification and circulation functions may be (1) included in a unitary closet structure, usable indoor or outdoor, (2) included as a modular unit for retro-fitting into an existing closet storage solution, or (3) a chassis that may be scaled and built into closets during their design and manufacture. The closet can include a sanitizing unit and may move air through a condenser, warm the dehumidified air, and deliver that treated air to a different portion of the closet, creating an air flow about the clothes hanging therein. A condensate collection unit may automatically shut down the system when a condensate reservoir is filled, thereby preventing condensate overflow. The closet may operate without the heat and/or dehumidification function, where external air may be circulated in and out of the closet.
